A prototype of Street Fighter 2: Special Championship Edition. It seems to have been dumped and modified by pirates. It likely was developed and scrapped then re-developed, possibly due to negative feedback from the press and/or because Street Fighter II: Turbo was announced for SNES, which had much more changes. This prototype seems to be a port of Champion Edition and did not have the changes made in Hyper Fighting (arcade) or Turbo (SNES). The cancellation of this prototype lead to a release date change from June 1993 to September 1993.
